| Abstract: | The concrete?filled double skin steel tubular column with square section under eccentric loads is studied in the paper Twelve pieces of the column are tested in the lab of Fuzhou University Outside square tube is made of four welded plates;inside is a weldless steel tube The concrete is sandwiched in between the two tubes The main parameters varied in the study are the slenderness ratio and the eccentricity of load It is found that the computed load?displacement relations are in good agreement with that of the test one At last,a simplified formula for the bearing capacity of the column is proposed in the paper |
